Sapphire is one of the most widely used and sought-after coloured gemstones in jewellery. A corundum with a hardness of 9/10, second only to diamond, it endures through generations without losing its brilliance — and comes in far more than blue: teal, pink, padparadscha, yellow, green, violet and orange. Bonnot Paris purchases its sapphires directly from its sourcing markets in Sri Lanka and Madagascar. Each stone is presented with its treatment information and available laboratory report (SSEF, GRS, ICA, Bellerophon, depending on the stone); diffusion and filling treatments do not meet our selection criteria. Choose your gemstone from our selection, from Ceylon blue sapphire to Madagascar teal sapphire, then imagine your stone set: discover our sapphire engagement rings, custom-made in our workshop.

FAQ — Sapphires

Contrary to popular belief, sapphire is not only blue: it exists in virtually every colour of the spectrum, except red — in which case it is called ruby, although it is the same mineral species (corundum). At Bonnot Paris, we work with seven main colours:

  • Blue sapphire — the great classic, from pale blue to deep royal blue. The most sought-after come from Kashmir (almost exhausted), Ceylon (Sri Lanka) and Burma.
  • Yellow sapphire — from pale lemon yellow to intense golden yellow, bright and sunlit. Main sources: Sri Lanka and Madagascar.
  • Pink sapphire — from pale pink to vivid pink. Padparadscha lies at the boundary between pink sapphire and ruby.
  • Padparadscha sapphire — the rarest and most precious of all, with its characteristic pinkish-orange hues evoking the lotus flower (hence its name in Sinhalese). Almost exclusively from Ceylon.
  • Teal sapphire — between blue and green, a deep, contemporary shade highly sought after for modern engagement rings. Mainly from Sri Lanka and Madagascar.
  • Violet sapphire — from lavender to deep violet, often confused with amethyst but much harder and more brilliant.
  • Green sapphire — from pale green to intense green, rarer in gem quality.

There are also white sapphires (colourless), black sapphires, and fancy sapphires in intermediate hues (orange, golden brown, blue-green). A remarkable optical phenomenon: some sapphires display a colour change depending on the light source (blue in daylight, violet under incandescent light) — these are “colour-change sapphires”, among the most precious.

This chromatic diversity makes sapphire one of the most versatile gemstones in jewellery — each colour having its own rarity, symbolism and price per carat.

Sapphire is an excellent choice for an engagement ring thanks to its great durability, second only to diamond. A symbol of fidelity, sincerity and lasting love, it also captivates with its timeless elegance and magnificent shades of blue. It is a refined, distinctive gemstone, ideal for everyday wear.

Each creation begins with a personalised consultation, in Paris, Angers or by video call, to understand your wishes, your story and your budget.

Our experts guide you in selecting the stones and developing the design of your jewel.

Our designers then create several sketches to help you visualise the piece.

Once the stones and design have been approved, our master jewellers handcraft your creation in our workshops, to the highest standards of excellence of Maison Bonnot Paris.

How does the bespoke creation process work?

Yes, all our stones are certified by renowned laboratories such as Bellerophon, ICA GemLab, London Gem Lab, and others, guaranteeing their authenticity and exceptional quality.

Are your stones certified?

Delivery is made in person in Paris or via a specialist carrier, to ensure secure, insured and fully reliable shipping to its destination.

How is my bespoke jewel delivered?

The production time depends on the complexity of the jewel, but generally takes between 4 and 8 weeks after approval of the final design.

Thanks to our offices in India, Sri Lanka and Bangkok, close to the markets and mines, we take the time needed to select the ideal stone, perfectly aligned with your expectations.

What are the creation lead times?

Yes, Bonnot Paris offers a recycling and transformation service for your jewellery.
We can reuse the gold from your existing pieces to give it a new life in a jewel designed especially for you.

Can I reuse my gold for my creation?

We assist many clients throughout France and internationally in creating bespoke jewellery.

A video consultation is initially offered to understand your wishes, expectations and project.

Thereafter, personalised support is provided via WhatsApp or email, to guide you at every stage.

We send you detailed photos and videos of the selected stones (or jewel), to reassure you in your choice.

You are also free to send us, by message or images, your inspirations, questions or doubts, and we remain at your disposal throughout the creation process.
